Hey
Very good game, however here two things that you might want to get fixed:
1) You can drag your squirell out of game area, so i can easily achieve starting boost by just resizing my window and positioning it at the leftmost side of screen.
2) Your special bar is filling right away after game start, so I can just wait untill it is full enough and then release squirell.
Apart from that, very good game. 10/10, 5/5 :)
